I went down a #uml, #sysml (v1 and v2), #kerml, #mbse rabbit hole last night.

All that I know now is that there is a place for it systems engineering principles, but not a great way to go from, this system needs x, y, z to auto-sizing switchboards, voltage systems, cable sizes, etc.

Do I know any Systems Engineers in the fediverse? I have a project that I'm working on/in that is more complex that my typical projects. One person that I was talking to on the project brought up that we should be using a model based approach, vs document based, and talked about UML, SysML, etc. I started looking around, and while I 'get' it, I'm not entirely sure how it will help my own process.

The next #Ontology Summit session on Wednesday 29 April 2026 will feature

Will Sobel

who will present

The Evolution of an Industrial Standard: From Paper to Ontology

As usual, all summit sessions are zoom sessions on Wednesdays at Noon US/Canada Eastern Time, and each session lasts one hour. The summit is open to the public and no registration is necessary. All summit sessions are recorded and are available on the summit web pages and on the Ontology Summit YouTube channel.

#sysML

@macberg Maybe give Gaphor a try?

(I pitch it as "Notepad for models" for rapidly making a design and haven't used it for complex systems.)

Modeling for Everyone

Gaphor is a UML, SysML, RAAML, and C4 modeling application written in Python. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool. You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models.

Gaphor, the SysML/UML modeling tool

while performing by duties,
creating architecture, modelling,
it became very clear,
why one need to use a formal language,
you find inconsistency,
why,
because you benefit from experience that build the formal language, countless hours and knowledge just ready to use

#MBSE #SysML

of course you need a tool as well
#MagicDraw

@ragman I mostly model in SysML v1, but it overlaps a lot with UML. So I start with PlantUML a lot when prototyping or for an everything-as-code approach.

SysML v2 has textual representation, though it reads a bit more like code then a markup language like PlantUML.

Does it make sense to use constraint blocks in #SysML parametric diagrams to show error probabilities? How would you connect such an error probability to a block that causes errors at the specified rate?
How would you model error cases in #SysML ? Most SW and HW parts that exist in a complex system can cause errors.
My spontenous idea would be to either not model these at all or to show these as regular control flows in e.g. activity diagrams. Is there a nicer way to do this?
